#18 Claims. (01. 30-201) The present invention relates to hair clippers and it has special reference to a device for attaching a comb to a hair clipper unit.

It is one of the principal objects of the improve ments to simplify the construction of a hair clipper such as contemplated herein, and to improve the efliciency, operation and dependability of such hair clipper.

It is also a principal object hereof to provide an attachment'ior mounting a comb onv a hair clipper in a manner'so that the comb maybe moved fiat uponthe scalp, and the clipper may the improvements contemplated herein will be be bodily tilted with respect to the comb for "determining the length of hair that is cutbythe clipper. -v

Another principal object. of the improvement is to provide a comb mounting device that may .be readily attached to a hair clipper without altering the structure of'the clipper. -.In this connection, the device is constructed, and ar-' ranged so thatthe comb may be. removed for replacement whenever desired witholit detaching the-device from. the clipper. ,y'

A further principal objecthereoi isto provide a comb attachment for a hair clipper that'eflects ating the hair; clipper may gradually tilt theclipper head while' cutting the hair in a given direction to progressively increase or diminish the length of hair that is severed, as for example,

or back of c ipper comb. 30*

apparent to persons skilled in the,art after the construction and operation of the comb attachment is understood from the within description.

It is preferred to accomplish the numerous objects of this invention and to practice the same in substantially the manner hereinafter fully described and as more particularly pointed out in ;the appended claims. Reference is now made to the accompanying drawing-that forms a part of this specification;

In the drawing: I I

s Figure 1 is a view in side elevation showing a hair clipper with the present invention mounted thereon and illustrating a manner of using the structure by tilting the clipper body on the comba Figure 2 is a view in perspective showing the Figure 4 is .a section on the plane of line 4-4 on Figure 3.

Figure 5 is a section on line 5-5 of Figure 3. Figure 6 is a view of a portion of the outer face The drawing is to be understood as being more o or less of aschematic character-for the purpose of disclosing a typical or preferred form of the improvements contemplated herein, and in the when using the clipper upward or downward on the neck. Another object is topi'ovide a comb attachdrawing the same reference characters identify the same parts in the different views.

" The hair clipper shown in Figure 1 comprises a cylindrical body 5 the forwardportion 6 of which is of reduced dimensions. This forward ment for a hair clipper wherein provision is made to prevent accumulation of hair in theattachment by providing ample clearance space between the comb and cutter head for shedding the hair clipp'er'that is constructed in a; simple and novel manner so that it. may bequickly assembled with'or removed from a hair clipper; that is'eifective for producing the deSiredlength of cut performed by theclipper; that allows the comb to be projected 'diflerent distances beyond vthe operating portion/of the clipper head; and

which may berreadily manufactured from metal stampings so thatit maybe sold at a reasonable retail price. ,y

portion terminates in-an.- extension -I having a relativelyflat top 8 with an oblique end upon -.which the usual cutter head is removably 'comb plate II. There is a shallow depression in the face of the omb plate that is bridged by the cutter plate, such depression providing a shoulder l2 back of the roots of the comb teeth as shown at the left in Figure -3. The present im-provement utilizes thisshoulderas an abutment or stop for mounting the comb attachment on the cutter head as will presently be explained herein.

The comb e seme ts shown in detail in Figures 2, 3 and v4, preferably comprises a suptime will permit of relative swinging movement between the hair comb 28 and the clipper.

When in use for cutting hair the comb 28 is adapted to be moved in a path while flat against 1 the scalp when the clipper is operating and the clipper is adapted to be tilted during the clipping operation to any angle desired with respect to the I2 above mentioned. The flanges I4 are spaced far enough apart to accommodate the sides of the comb plate I I between them, and, as seen in Figure 3, the supporting plate I3 has its forward edge curved inward as at I 6 between its side edges or flanges.

The rear portion of supporting plate I3 has spaced slits I1, preferably diverging outwardly to provide a fan-shaped spring leaf I8 therebetween with an arcuate outer margin that is bent upwardly in the form "of a retainer lip I9. The

portion of the comb plate I I farthest from its' teeth has a curved edge against which the retainer lip I9 is engaged when the attachment is mounted on the cutter head of the hair clipper, and in order to facilitate the ready mounting and demounting of the attachment there is a lateral finger piece 2I formed on the central or midportion of the retainer lip I9.

. A suitable slide is movably mounted on the supporting plate I3 for movement towards and away from the forward or work portion of the cutter head and beneath the supporting plate. This slide comprises a cross-b r 22 the ends of which are bent upwardly as at 23 alongside the flanges ll of the supporting plate, and they are then turned down over the edges of the flanges as at 24, thus maintaining the slide in-movable relation tothe plate I3. In order to accommodate the flexing movement of the spring leaf I8 the latter is deflected or slightly crowned as at 25 so that it is out of the plane of the adjacent portion of the supporting plate l3. Suitable finger pieces 26 are formed at the ends of the crossbar 22 by tubing or rolling a portion of the' metal from which the cross-bar is fabricated. Also the ends of the cross-bar are provided with pendent ears 21 that project downwardly away from the bar as shown in Figures 2 and 4.-

The slide member above described is adapted to hingedly support a holder or carrier for a hair comb 28 of the usual construction with a plurality of teeth 29 and a back 30 connecting the roots of the teeth. This carrier preferably em-' bodies a metal strip 3| having its ends bent into a U-shape form to provide yieldable facing clips 32 into which the end edges of the comb back 30 are inserted and frictionally held in position. The carrier has ears 33 at its ends projecting away from the clips 32 and arranged in overlap-- comb 28. This will predetermine the length of' hair that is removed, and it is especially effective y when clipping the hair adjacent the neck and back of the headfor the reason that the clipper may. be moved in an upward path and graduallytilted to progressively remove less and less hair while the clipper is traveling along such path. It will also 'be seen that the back 30 of the hair comb 28 is spaced a considerable distance from the clipper head so that there is little or no acdirect or guide these strands to the teeth of the cutter head where they will be severed by the action of thetoothed vibratory cutter plate I 0. By moving the slide outwardly the tips of the comb teeth. 29 may be projected different dischannels Ila so that these regions of the cutter.

the pivots 34 with'one'of its ends 38 pressed ainst the slide or other portion of the attachment, and the other end 3'I'of the spring is selectively seated in one of a series of notches 38 in the adjacent ear 33 to increase or diminish the tension of the spring. As seen in Figure 4, the reflex action of the spring is utilized to normally urge the teeth 29 of the hair comb 28 towards the teeth of the clipper comb teeth, but atthe same tances beyond the points of the teeth on the clipper head comb plate II. This will determine the fineness of the cut made by the clipper and avoids the necessity of having to provide interchangeable clipper heads for different cuts while out. ting-a persons hair. The present improvements thus will effectively perform the various functions of a series of interchangeable clipper heads such as at present are required.

It frequently may be desired to maintain the hair comb 28 in fixed relation to the cutter head, and in order to accomplish this provision is made to lock the comb 28 so that there is no relative movement between. it and the cutter head. The pivot or trunnion 34 has an inner head. 38 (Fig ure 5) that is anchored by welding or' o herwise to the inner surface of the ear 32 and its shank is threaded to receive a knurled thumb nut 48 that is screwedthereon' to draw the ears 2! and 32 into firm frictional contact thereby locking the-nor -mally movable parts against relative movement.

In order to'prevent accidental removal of the thumb nut 40 the outer end of the trunnion is upset as at II to act as a retainer for the thumb nut.

As shown in Figure 6, the back or outer face of the cutter head comb plate II is provided with longitudinal parallel channels Ila. that extend rearwardly away from the roots of the teeth, and since thesupporting plate I3 01' the comb attachment is disposed across these channels provision is herein made to prevent clipped hairs or other. extraneous particles accumulating in these channels- To this end the leading marginal region of the plate I3 is provided with corrugations l3 a that. arespaced in the same arrangement as the head comb plate II and the opposing surface of the attachment plate I3 will be snugly fitted to each other. This arrangement-also assists in maintaining the members in such intimate relation to each other that vibration 'chatter oi. the parts is prevented. While the present invention has been described in detail in its present preferred form or embodiment, it will beapparent to persons skilled in the art, after understanding the improvements con-- templatedfherein, that various changes and modifications may lbel'ma-d ltherein swithout :de- ,.parting ffrom :the: spirit'aior e'scope :th'ereof.
